HIgh memory usage in odm_orthophoto module for diagonal corridor patterns

[pierotofy]

Diagonal corridor patterns take a huge amount of memory to render with odm_orthophoto (https://github.com/OpenDroneMap/odm_orthophoto) and this could be improved. Possible ways:

• Tiling like we do for DEMs
• Rotate the corridor so that it fits in an axis-aligned square, render it, then rotate it back (?)
